Ok, the rundown is.

I work for a company that hired me as an independent contractor.
I filled out a W-9 (i think) form, to stop the feds from taking %20 auto.
I normally do not pay any taxes, I never have. I always get everything back.

So... how to i go about my taxes for this year? I would assume I am going to file as a "home business" and claim my income. I should end up owing nothing...

Anyone know if there is anything i should do? Do i need to apply for some sort of IRS ID or something?

And do i need to start my own business, or is that already done? I don't really do anything and I don't need a tax exemption for purchases.
